To'aZZ whom it may concern:

Be it known that I, CHARLES VALLONE,.3. citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Improvement in Antirattling Devices forSliding-Side Cribs, of which the following is a specification.

This invention relates more particularly to anti-rattling devices forchildrens metal cribsof that kind having sides or side ,railingsarranged to slide up and down on vertical guide rods which are fixed tothe end frames of the crib and passthrough guide holes or loops on thehorizontal railsof the sliding side.

The object of the invention is to provide a practical and desirabledevice of siinple and inexpensive construction and which isinconspicuous, for preventing the slidingside from rattling on its guiderods in the use of the crib.

In the accompanying drawings: Figure l is a fragmentary broken sideelevation of a crib provided with anti-rattling devices embodying theinvention. Fig. 2 is a sectional plan View thereof on an enlarged scaleon line 22, Fig. 1. Fig. 3 is a sectional elevation thereof on line 83,Fig. 2.

Like reference characters refer to like parts in the several figures.

A represents the upright end frames, and B one of the sliding sides orside railings of a metal crib of ordinary construction. The side B shownconsists, as usual, of horizontal upper and lower rails 72 I) connectedby uprights 12 and is arranged to slide on vertical uide rods O whichare fixed to the end frames and pass through guide holes 0 in the endsof the upper rail and through guide holes or loops 0 at the ends of thelower rail of the side B.

As the distance between the guide rods or between the guide holes orloops atthe ends of the sliding side are apt to vary somewhat in themanufacture of the cribs, the guide holes or loops are ordinarily madesufliciently larger than the cross-section of the guide rods to enablethe parts to be readily assembled and insure the free sliding of theside on the guide rods. There is, therefore, frequently suflicient playof the holes or loops on the guide rods to cause objectionable noise orrattling in the use of the cribs. This play and rattling is prevented bythe following described means: D represents anti-rattling devices orsprings secured to the lower rail of the sliding side and pressmgyieldingly against the guide rods C for preventing the play and rattling of the lower portionof the side against the guide rods. Each ofthesprings shown consists of a strip of spring metal having a broadattaching end (Z (Figs. 2 and 3) which extends along andis preferablycurved to conform to the cylindrical surface of the lower rail adjacentto the loop 0 and isriveted or otherwise rigidly secured thereto.Preferably the lower rail has an integral rivet stud cl which passesthrougha holein the spring strip and is headed over. The spring extendsfrom its attachedend toward the guide rod C and its free end curves 0rbends down-v wardly into the loop or hole 0' and bears yieldinglyagainst'the inner side of the guide rod, thereby drawing the end. of theloop against the outer side of the rod and preventing the loop fromrattling against the guide rod. As the spring strip lies flat upon therail 6 and its free end enters and is practically hidden from view bythe loop 0, the device is very inconspicuous and does not detract fromthe neat appearance of the crib. Furthermore, the free end of the springis confined between the sides of the loop and is thus prevented fromlateral displacement from the guide rod and it is practically impossiblefor the spring to be accidentally knocked out of position against theguide rod or broken, as would be liable to happen to a spring projectingupwardly or away from the rail. The spring can thus be securely fastenedin place by a single rivet and cannot get out of place even if itshouldbecome loose on the rivet. The device described is, therefore,exceedingly simple and inexpensive to apply to the cribs and is reliablein use and durable. The spring exerts suflicient pressure against theguide rod to prevent the loop rattling-on the rod but it is adapted toslide along the rod and not interfere with the raising or lowering ofthe side on its guides.

Anti-rattling devices similar to those on the lower rail can, ifdesired, be applied to the upper rail 1) also, to prevent the rattlingof the upper portion of the side on the guide rods, but in the cribillustrated the upper rail is provided with clutches E engaging theguide rods for holding the sliding side in any position to which it-inaybe raised, and as these clutches prevent play and rattling of the upperportion of the. side on the guides it is not necessary to use theantirattling springs D on the top rail. The clutches E shown consist ofpivoted levers which are caused to grip the guide rods by hidden springsand they are adapted to be released to permit the lowering. of the sideby pressing upwardly the inner ends of the levers. v I

I claim as my invention: v 1 l. The combination with'the' sliding sideof a crib having a horizontal rail, and a guide rod on which said railis arranged to slide, of a spring strip which is secured to and extendslengthwise of said rail and has a bent free end which bears yieldinglyagainst said guide rod and is adapted to slide thereon.

2. The combination with the sliding side of a crib; and a'guide rodwhich passes through a guide hole in said side, of a spring stripsecured to said'side and having a free end which extends into said holeand bears yieldingly against said guide rod and is adapted to slidethereon.

3. The combination'with the sliding side i of a cribhaving a horizontalrail; and a guide rod which passes through a guide hole strip beingheld'from lateral displacement by the walls of said hole.

4. The combination with the sliding sideof a crib having a horizontalrail, and a guide rod whlch passes through a gulde hole in said rail, ofa spring strip having an .at-

taching portion-which lies fiat against said rail and 1s secured theretoby a smgle rivet and a bent free end which extends into said hole andbears yieldingly against said guide rod and is adapted to slide thereon,the free end of said spring strip being held from lateral displacementby the walls of said hole."
